The SuperCDMS Soudan high threshold WIMP search and the planned SuperCDMS SNOLAB experiment

[摘要] There is ample evidence that visible matter cannot account for a large component of the mass in the universe. Weakly Interacting Massive Particles (WIMPs) are one popular hypothesis to account for the missing mass. The Super Cryogenic Dark Matter Search (SuperCDMS) experiment is designed to directly detect WIMPs through interactions with a nucleus in a target crystal. The SuperCDMS detectors are instrumented with phonon and charge sensors, enabling excellent rejection of electron-recoil backgrounds. Approximately 3000 kg-days of exposure have been collected with the SuperCDMS Soudan experiment. We will describe the search for WIMPs with masses between 10-100 GeV and work towards the SuperCDMS SNOLAB experiment.
